UNITED STATES WILLIAM J'. BURKE, OF SAN FRANCISCO, CALIFORNIA.

PEG FOR VIOLINS AND THE LIKE.

Application filed March 16, 1920.

To all whom it may concern Be it known that I, VILLIAM J. BURKE, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Peg for Violins and the like, of which the following is a specification.

This invention relates to pegs for use in connection with violins and similar musical instruments, one of the objects of the invention being to provide a simple form of lock which may be combined with pegs already in use and whereby unwinding of the string connected to the peg can be prevented.

Another object is to provide a locking structure of this character which is simple and compact in construction and will not readily get out of order.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a longitudinal section through a peg having the present improvements combined therewith.

Fig. 2 is an enlarged section on line 2-2, Fig. 1.

Fig. 3 is a detail view, in plan, of the locking spring.

Referring to the figures by characters of reference 1 designates an. ordinary peg in which is cut a short longitudinal channel 2. Mounted on this peg is a band 3 the ends of which are inturned as at a and are adapted to be seated within the channel 2 and to bear against the walls of the channel as shown. These inturned ends constitute wear or guide flanges and are connected, adjacent one end, by a cross pin 6 on which is pivotally mounted one end of a spring catch 7. This catch is formed of a single length of spring metal folded upon itself, as at 8 to provide a supporting tongue 9 the end of which rests upon the bottom of the channel 2. A short lip 10 is bent upwardly from one edge of the strip 7 and is normally proj ected beyond the circle defined by the peg 1.

Specification of Letters Patent.

Patented Aug. 31, 1920. Serial No. 366,247.

That portion of the peg on which the band 3 is mounted is adapted to rotate within a sleeve 11 provided with an attaching flange 12 whereby it may be secured to the neck of the musical instrument. This sleeve is provided, on its inner surface, with an annular series of ratchet teeth 13 adapted to be engaged by the lip 10 on the spring stri 7. A projection or enlargement 14L may be formed on the strip 7 at the fold 8 thereof so as to constitute a finger piece, this linger piece being located in the same plane with the annular groove 15 which is ordinarily provided in the peg.

In using the device the peg is inserted as ordinarily, thus bringing the lip 10 within the sleeve 11 and in engagement with one of the teeth 13. Obviously by turning the peg in a clockwise direction the lip 10 will slip over the teeth 13 and prevent counter clockwise movement of the peg. However should it be desired to disengage the lip 10 from the teeth so as to permit the spring to be unwound from the peg, it would merely be necessary to depress the finger piece 14. This would cause the strip 7 to move down into the channel 2 against the action of the supporting tongue 9, thereby shifting the lip 10 inwardly away from the teeth 13.

It will be noted that the structure is very simple, durable and compact and is advantageous because of the ease with which it can be applied to pegs already in use.

W hat is claimed is:

1. The combination with a sleeve having an annular series of internal ratchet teeth, of a peg having a longitudinal channel, a band extending around the peg and having inturned ends seated in the channel, a yieldingly supported member mounted between and carried by said inturned ends and normally engaging the ratchet teeth to hold the peg against rotation in one direction.

2. The combination with a sleeve having an interior series of ratchet teeth, of a peg having a channel, a band extending around the peg and having inturned ends seated in the channel, a spring member pivotally mounted within the channel and between said ends, a yieldable support for said mem ber, a finger piece upon the member and outside of the channel, and means on the member for engaging the ratchet teeth to hold the peg against rotation in one direction.

3. The combination with a sleeve having an interior series of ratchet teeth, of a peg insertible into the sleeve and having a longirotation in one direction, and a finger piece tudinal channel, a band extending around upon the fold portion of the strip and yield the peg and having inturned ends seated in ingly supported outside of the channel.
